This book is the first collection of papers on Slavic language within a formal non-transformational linguistic formalism. The articles presented here are concerned with all components of grammar, from semantics, through syntax and morphology, to phonology. In particular, the following phenomena are given HPSG analyses: syntax and semantics of negation, anaphor binding, syntax and morphology of auxiliaries, {em wh}-extraction, syntax and morphology of case assignment, diathesis and voice, complement vs. adjunct distinction, and syntactic haplology. The main languages dealt with are Polish and Serbo-Croatian, but Russian, Czech and Bulgarian are also represented.
